78-17157-02

Installation and Configuration

These controllers offer the highest level of performance and scalability for large-scale enterprise WLAN

deployments. In addition, these controllers deliver WLAN services over an existing ethernet or IP

infrastructure, protecting existing network investments while providing best-in-class wireless services.

As a core component of the award-winning Cisco Wireless LAN Solution, these controllers deliver

wireless security, intrusion detection, RF management, Quality of Service (QoS) and mobility across an

entire enterprise. It works in conjunction with other controllers, Cisco WCS, and access points to provide

network managers with a robust Wireless LAN (WLAN) solution that enables business-critical wireless

applications. From voice and data services to location tracking, the controllers provide the control,

scalability, and reliability that IT managers need to build secure enterprise-scale wireless networks.

This document is written assuming that you have already determined the 802.11 topology. Because the

Radio Resource Management (RRM) feature automatically detects and configures the access points as

they appear on the network, it is not necessary to have any access points on the network to install and

configure a controller.

The controller is 17.5 in. wide x 15.75 in. deep x 1.75 in. high (443 x 400 x 44.5 mm). The chassis can

be rack or shelf mounted.

Controller Models

The controller comes in 2 variants—4402 and 4404.

The 4402 Cisco Wireless LAN Controller has two front-panel slots for 1000BASE-SX, 1000BASE-LX,

or 1000BASE-T SFP modules. The 1000BASE-SX SFP Module provides 1000 Mbps wired connections

through 850nM (SX) fiber-optic links using LC physical connectors. The 1000BASE-LX SFP Module

provides 1000 Mbps wired connections through 1300nM (LX/LH) fiber-optic links using LC physical

connectors. The 1000BASE-T SFP Module provides 1000 Mbps wired connections through CAT-5,

CAT-5e, CAT-6, or CAT-7 cables using RJ-45 physical connectors.

The 4404 controller has four front-panel slots for 1000BASE-SX, 1000BASE-LX, or 1000BASE-T SFP

modules, as described in Quick Start Guide: 1000BASE-SX, 1000BASE-LX, and 1000BASE-T SFP

Modules for Cisco 4400 Series Wireless LAN Controllers.
